I think there’s a more general point here about the tendency to teach specific knowledge, rather than fundamental knowledge along with the skills to generalize it, but I’m too tired to come to any real conclusion right now.
There’s a metaphor here, if you want there to be, about how to structure your life to make things easy on yourself. Starting a bike tour is a hard decision, but once you’re on a bike, pedaling is all you can do. If you want to be able to do things that are hard, structure them so that the difficult choices are made up front, and the automatic action to take moves you towards your goal. Figuring out how to apply this lesson to your life is left as an exercise for the reader.
